[Rescheduled] Firmware updates for all-flash SAN storage - September 27, 2022
Posted by David Cunningham on 22 September 2022 07:03 PM
Purpose of Work:

Tonight, at 9 PM MDT, we will be performing a routine firmware upgrade on one of our all-flash SAN units, to get it on the latest firmware and security update level.

This will a continuation of the maintenance done on the 22nd, which had to be rescheduled.

Impact of Work:

No impact is expected.  The unit will be automatically updating a single controller at a time, meaning it should be failing over gracefully to the other controller at any given phase of the updates.

We have performed this upgrade on two non-production SAN units earlier today, and no impact occurred.

If any impact occurs, you may see degraded performance or an outage on certain standalone hypervisors, or lower-volume clusters.

We will be monitoring the process closely for any issues to mitigate and will update this news post, if we notice anything of the sort.

Please contact us with any questions / comments / concerns.
